In some in'stl'nces, where economy in the amount of glass employed, or shallowness of the lenses is desired, some saving in this regard inay be effected by archin the'body portion l1 of the foundation memliers somewhat, as shown in Fig. 3, leaving a central planar zone llonly of sufiicient width to receive the glass'and providing downwardly deflected portions 11 flanking said planar portions on both sides and jmeetin angu arly, or iuer ing into, the vertical si elwalls 13 and 14. n construction the platform is not horizontal throughout, but' its variation from horizontal may be slight and the arrangement, witli the bodies meeting shoulder to shoulder, provides a continuing plat# forni and embodies many salient advantages of the structure first described.

If desired t-he sections ma be made as shown in Fig. 4, both side wa ls of one section being provided with edge lips as'at 15, and both side walls of the next section being plain as at 18".v a

n some installations it is desirablefto have the reinforced concrete alone support the lenses in the completed structureywith' out 4the provisionof a ermanentmetallic foundation and forsuc construction the foundation sections 'described maybe employed as part'of, the tem orary false work to support and position t e lenses and cement in the process oferection of the-rein'-v forced-concrete structure. For such work it has heretofore been customary to employ templets of-paste board,'sup orted upon a wood backing, to position' t e glasses and define the lower surface of the cement, the false work, includin the paste board,'being removed after the ass is in place and the cementhardened. he asteboardisusually employed in large shee and is disadvanta cous on account of expense,`being usable on y once. Sheet metal yhas heretofore iroved to be an unsatisfactory substitute lor the aste board, however, in that it cannot easi be maintained smooth and level in flat p ates, and is difiici'ilt to handle and ship in such form. The paste boardma readily be brought to level` on the wood backing, but a metal sheet when once'buckled is verv dillicultfto' bring `down to the' desired atness, or to'le'vell on'the wood backing; The"A foundation units, lof-"iiiyfinven tion lmay.fhovqever,\.fbe, employed 1 satisfaci false work may assemb ing. In such temporary use ot the foundation sections, they are arranged to 'receive support in any suitable manner from a false work bracing, thatI herein shown for illustration, providing edgeframe members 30,'hung on metal clips 31 as a convenient and chea i arrangement for support of the edffes of tie sectional metalfoundat-ion. refer-ably the metallic foundation structure when assembled is smaller iii every direction than the aperture in which the glass lights are to be alaced, and is supported on the frame 30 an shiins 30',the o en border s aces around seine or all of t e edges of t e metallic foundation structure being brought to a level with the )lanar port-ion of the metallic foundation removable border strips 32 of wood. The slight cracks or creviees in the surface of the metal foundation at the lines of articulation of the sections, may be leveled with sand, or any appropriate power, well known in the art to which the cement. will not readily adhere, as exaggeratedly shown .at 83, and the clips 31 may be protected bv sandin or greasing, so that the cement will not a here thereto. When the desired smooth surface is thus attained the placing and setting of the lenses, rods, and cement are accomplished in the manner heretofore described. When the cement has set the all be taken down and the metal foundation, free from support at all of its edges, may be directly removed from the cement, leaving the reinforced cement with its embedded enses in a self-supporting span across the orifice of the side walk, receiving its bearing directly from the sidewalk.

While I have herein dcscribed in some detail specific embodim'ents of my invention for purposes of full disclosure, it will be apparent to those skilled in the art that many changes in the specific organization might be-'made without departure from the s irit of my inventionand within the scope o the ap ended claims.

at I claim is:

1. In a structure of the character described the combination of a metallic foundation structure comprising a lnralit of sections, each section consstingo a strip iavin a body ortion provided with apertures, an vertica ly down-turned flanges at its edges, one said flange having an upturned lip at its lower edge embracin the downwardly facing lower edge of ie op osite flange of the next adjoining section, an said flanges contacting face to face above their` spaces between the lenses, and a cement body laterally surrounding the blocks and embedding the reinforcin rods, and having its lower surface define by the metallic reinforcing structure.

2. 'In a vault light structure the combina-l tion of a metallic foundation comprising a plurality of sections each having an apertured body portion `and down-turned side Walls on opposite sides of the body portion, the side walls of adjoining sections interlocking at their lower edges, and meeting face to face above their lower edges, lenses cement body surrounding said lenses above the foundation. j

4. A foundation element of the character described, consisting of a strip of sheet metal having down-turned side walls, one of said side walls having anu turnedoutwardly-extending lip forming4 a narrow channel 16 at substantially lthe same depth v as the edge of the opposite side wall, said strip having between its side walls a body portion having .lens receiving apertures therein. l

5. In a Ivault light structure, a metal foundation comprising a plurality of relatively narrow sections each having an aperturedg lens-receiving body portion and downturned side walls, said body portions meeting shoulder to shoulder to form jointly a transversely continuous platform, and means to connect face to face the proximate side walls of adjoining sections below said shoulders.

In testimony whereof I hereunto set my'v hand in the presence of two witnesses,v
